Really swap arguments #4 and #5 in stub32_clone instead of
"optimizing" it into a move.
Yes, tls_val is currently unused. Yes, on some CPUs XCHG is a
little bit more expensive than MOV. But a cycle or two on an
expensive syscall like clone() is way below noise floor, and
this optimization is simply not worth the obfuscation of logic.
[ There's also ongoing work on the clone() ABI by Josh Triplett
that will depend on this change later on. ]

SYSENTER and SYSCALL 32-bit entry points differ in handling of
arg2 and arg6.
SYSENTER:
* ecx arg2
* ebp user stack
* 0(%ebp) arg6
SYSCALL:
* ebp arg2
* esp user stack
* 0(%esp) arg6
Sysenter code loads 0(%ebp) to %ebp right away.
(This destroys %ebp. It means we do not preserve it on return.
It's not causing problems since userspace VDSO code does not
depend on it, and SYSENTER insn can't be sanely used outside of
VDSO).
Syscall code loads 0(%ebp) to %r9. This allows to eliminate one
MOV insn (r9 is a register where arg6 should be for 64-bit ABI),
but on audit/ptrace code paths this requires juggling of r9 and
ebp: (1) ptrace expects arg6 to be in pt_regs->bp;
(2) r9 is callee-clobbered register and needs to be
saved/restored around calls to C functions.
This patch changes syscall code to load 0(%ebp) to %ebp, making
it more similar to sysenter code. It's a bit smaller:
text data bss dec hex filename
1407 0 0 1407 57f ia32entry.o.before
1391 0 0 1391 56f ia32entry.o
To preserve ABI compat, we restore ebp on exit.
Run-tested.

path
32-bit syscall entry points do not save the complete pt_regs struct,
they leave some fields uninitialized. However, they must be
careful to not leak uninitialized data in pt_regs->r8..r11 to
ptrace users.
CLEAR_RREGS macro is used to zero these fields out when needed.
However, in the int80 code path this zeroing is unconditional.
This patch simplifies it by storing zeroes there right away,
when pt_regs is constructed on stack.
This uses shorter instructions:
text data bss dec hex filename
1423 0 0 1423 58f ia32entry.o.before
1407 0 0 1407 57f ia32entry.o

The wrmsrl_safe macro performs invalid shifts if the value
argument is 32 bits. This makes it unnecessarily awkward to
write code that puts an unsigned long into an MSR.
Convert it to a real inline function.

On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically
only in the 0-1 range dividing this by 2 results in a range of 0-0.
And even for v7 devices where this does not lead to making the trackstick
entirely unusable, it makes it twice as slow as before we added v7 support
and were using the ps/2 mouse emulation of the dual point setup.
If some kind of generic slowdown is actually necessary for some devices,
then that belongs in userspace, not in the kernel.

The patch fixes a bug in the default configuration which
prevented a software bridge loaded on the PF interface from
working correctly because broadcast packets are incorrectly
looped back.
Fix the general case, by loading the driver in VEPA mode Until a
VF or VMDq VSI is added. This way loopback on the Main VSI is
turned off until needed and can resolve the issue of unnecessary
reflection for users that do not have VF or VMDq VSIs setup.
The driver must now coordinate the loopback setting for the Flow
Director (FDIR) VSI to make sure it is in sync with the current
VEB or VEPA mode setting.
The user can still switch bridge modes from the bridge commands and
choose to be in VEPA mode with VF VSIs. Because of hardware
requirements, the call to switch to VEB mode when no VF/VMDqs are
present will be rejected.
NOTE: This patch uses BIT_ULL as that is preferred going forward,
a followup patch in the lower priority queue to net-next will fix
up the remaining 1 << usages.

This patch fixes a bug where the i40e Tx queue will hang if this
skb is passed to the driver.
With mixed size fragments while using TSO there was a corner case
where we needed to linearize but we were not. This was seen with
iSCSI traffic and could be reproduced with a frag list that looks
like this:
num_frags = 17, gso_segs = 17, hdr_len = 66,
skb_shinfo(skb)->gso_size = 1448
size = 3002, j = 1, frag_size = 2936, num_frags = 17
size = 4268, j = 1, frag_size = 4096, num_frags = 16
size = 5534, j = 1, frag_size = 4096, num_frags = 15
size = 5352, j = 1, frag_size = 4096, num_frags = 14
size = 5170, j = 1, frag_size = 4096, num_frags = 13
size = 3468, j = 1, frag_size = 2576, num_frags = 12
size = 750, j = 1, frag_size = 112, num_frags = 11
size = 862, j = 2, frag_size = 112, num_frags = 10
size = 974, j = 3, frag_size = 112, num_frags = 9
size = 1126, j = 4, frag_size = 152, num_frags = 8
size = 1330, j = 5, frag_size = 204, num_frags = 7
size = 1534, j = 6, frag_size = 204, num_frags = 6
size = 356, j = 1, frag_size = 204, num_frags = 5
size = 560, j = 2, frag_size = 204, num_frags = 4

In the functions compat_get_bitmap() and compat_put_bitmap() the
variable nr_compat_longs stores how many compat_ulong_t words should be
copied in a loop.
The copy loop itself is this:
if (nr_compat_longs-- > 0) {
if (__get_user(um, umask)) return -EFAULT;
} else {
um = 0;
}
Since nr_compat_longs gets unconditionally decremented in each loop and
since it's type is unsigned this could theoretically lead to out of
bounds accesses to userspace if nr_compat_longs wraps around to
(unsigned)(-1).
Although the callers currently do not trigger out-of-bounds accesses, we
should better implement the loop in a safe way to completely avoid such
warp-arounds.

After GPU reset, HW is losing the address of HWS page in the register.
The page itself is valid except that HW is not aware of its location.
[ 64.368623] [drm:gen8_init_common_ring [i915]] *ERROR* HWS Page address = 0x00000000
[ 64.368655] [drm:gen8_init_common_ring [i915]] *ERROR* HWS Page address = 0x00000000
[ 64.368681] [drm:gen8_init_common_ring [i915]] *ERROR* HWS Page address = 0x00000000
[ 64.368704] [drm:gen8_init_common_ring [i915]] *ERROR* HWS Page address = 0x00000000
This patch reloads this value into the register during ring init.

MMC_PM_KEEP_POWER doesn't imply MMC_PM_WAKE_SDIO_IRQ, we should only
enable device wake up when MMC_PM_WAKE_SDIO_IRQ is set. And "pm_flags"
is the requested pm features, we should not set it in the host driver.
At the same time, device wakeup is disabled by default, so there's no
need to disable device wakeup explicitly.
This patch fixes the warning as following:

Other subsystem buses attach PM domains during probe, but prior calling
the driver's ->probe() method. During the removal phase, detaching the PM
domain will be done after invoking the driver's ->remove() callback.
Convert the SDIO bus to follow this behavior and add error handling.

Since the ->reset() callback is implemented for SD, the ->power_restore()
callback has become redundant, let's remove it.

421b3885bf6d56391297844f43fb7154a6396e12 "udp: ipv4: Add udp early
demux" introduced a regression that allowed sockets bound to INADDR_ANY
to receive packets from multicast groups that the socket had not joined.
For example a socket that had joined 224.168.2.9 could also receive
packets from 225.168.2.9 despite not having joined that group if
ip_early_demux is enabled.
Fix this by calling ip_check_mc_rcu() in udp_v4_early_demux() to verify
that the multicast packet is indeed ours.

We currently do the IV seeding on the first givencrypt call in
order to conserve entropy. However, this does not work with
DRBG which cannot be called from interrupt context. In fact,
with DRBG we don't need to conserve entropy anyway. So this
patch moves the seeding into the init function.

Reduce the nx-842 pSeries driver minimum buffer size from 128 to 8.
Also replace the single use of IO_BUFFER_ALIGN macro with the standard
and correct DDE_BUFFER_ALIGN.
The hw sometimes rejects buffers that contain padding past the end of the
8-byte aligned section where it sees the "end" marker. With the minimum
buffer size set too high, some highly compressed buffers were being padded
and the hw was incorrectly rejecting them; this sets the minimum correctly
so there will be no incorrect padding.

draft-ietf-ipsecme-chacha20-poly1305 defines the use of ChaCha20/Poly1305 in
ESP. It uses additional four byte key material as a salt, which is then used
with an 8 byte IV to form the ChaCha20 nonce as defined in the RFC7539.
